Zukhov's favorite weapon was the Serbian-made Zastava M85. Zukhov believed it to be Russian-made, perhaps because he got it confused with the similar AKS-74U, the assault-carbine version of the Russian AK-74 assault rifle. The line might be a tongue-in-cheek reference to Lieutenant Pavel Chekov on Star Trek: The Original Series, who often claimed advanced technologies (even if they were Alien-created) were originally invented in Russia.
